Driving and operating181Press Engine Start/Stop briefly: an
automatic procedure operates the
starter with a short delay until the engine is running.
To switch off the engine when vehicle
is stationary, press
Engine Start/Stop briefly. Automatic
transmission: apply the parking brake
and engage P.
To start the engine during an
Autostop:
Manual transmission: during an
Autostop, the engine can be started
by depressing the clutch pedal
3 182.
Automatic transmission: during an
Autostop, the engine can be started
by releasing the brake pedal 3 182.
Emergency engine shut off during driving
If the engine needs to be switched off during driving in case of emergency,
press Engine Start/Stop for more than
two seconds or press twice briefly
within five seconds.9 Danger
Switching off the engine during
driving may cause loss of power
support for brake and steering
systems. Assistance systems and
airbag systems are disabled.
Lighting and brake lights will
extinguish. Therefore power down the engine and ignition while
driving only when required in case of emergency.
Starting the vehicle at low
temperatures
Starting the engine without additional
heaters is possible down to -25 °С for diesel engines and -30 °C for petrol
engines. Required is an engine oil
with the correct viscosity, the correct fuel, performed services and a
sufficiently charged vehicle battery.
With temperatures below -30 °C the
automatic transmission requires a
warming phase of approx.
five minutes. The selector lever must
be in position P.
Automatic Starter Control
This function controls the engine
starting procedure. The driver does
not need to hold Engine Start/Stop
pressed. Once applied, the system
will go on starting automatically until
the engine is running. Because of the checking procedure, the engine startsrunning after a short delay.
Possible reasons for a non-starting
engine:
● Clutch pedal not operated (manual transmission).
● Brake pedal not operated or selector lever not in P or N
(automatic transmission).
● Timeout occurred.
Turbo engine warm-up
Upon start-up, engine available
torque may be limited for a short time, especially when the engine
temperature is cold. The limitation is
to allow the lubrication system to fully
protect the engine.

Driving and operating185Caution
After running at high enginespeeds or with high engine loads,
operate the engine briefly at a low load or run in neutral for
approx. 30 seconds before
switching off, in order to protect
the turbocharger.
Note
In the event of an accident with
airbag deployment, the engine is
turned off automatically if the vehicle
comes to a standstill within a certain time.
Engine exhaust9 Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Exhaust filter
The exhaust filter is a particle filter for diesel and gasoline engines.
Automatic cleaning process
The exhaust filter system filters soot particles out of the exhaust gases.
The system includes a self-cleaning
function that runs automatically
during driving without any notification. The filter is cleaned by periodically
burning off the soot particles at high
temperature. This process takes
place automatically under set driving
conditions and may take up to
25 minutes. Typically it needs
between seven and twelve minutes.
Autostop is not available and fuel
consumption may be higher during
this period. The emission of smells
and smoke during this process is
normal.
System requires cleaning Under certain conditions, e.g. drivingshort distances, the system cannot
clean itself automatically.
If cleaning of the filter is required and
if previous driving conditions did not
enable automatic cleaning, it will be
indicated by a warning message in
the Driver Information Centre.

334Customer informationDepending on technical equipment
level, the data stored is as follows:
● system component operating states (e.g. fill level, tyre
pressure, battery status)
● faults and defects in important system components (e.g. lights,
brakes)
● system reactions in special driving situations (e.g. triggering
of an airbag, actuation of the
stability control systems)
● information on events damaging the vehicle
● for electric vehicles the amount of
charge in the high-voltage
battery, estimated range
In special cases (e.g. if the vehicle
has detected a malfunction), it may be
necessary to save data that would
otherwise just be volatile.
When you use services (e.g. repairs,
maintenance), the operating data
saved can be read together with the
vehicle identification number and
used when necessary. Staff working
for the service network ( e.g. garages,
manufacturers) or third parties (e.g.breakdown services) can read the
data from the vehicle. The same
applies to warranty work and quality
assurance measures.
Data is generally read via the OBD
(On-Board Diagnostics) port
prescribed by law in the vehicle. The operating data which is read out,
documents the technical condition of
the vehicle or individual components
and assists with fault diagnosis,
compliance with warranty obligations
and quality improvement. This data,
in particular information on
component stress, technical events,
operator errors and other faults, is
transmitted to the manufacturer
where appropriate, together with the
vehicle identification number. The
manufacturer is also subject to
product liability. The manufacturer
potentially also uses operating data
from vehicles for product recalls. This
data can also be used to check
customer warranty and guarantee
claims.
Fault memories in the vehicle can be
reset by a service company when
carrying out servicing or repairs or at
your request.Comfort and infotainment
functions
Comfort settings and custom settingscan be stored in the vehicle and
changed or reset at any time.
Depending on the equipment level in
question, these include
● seat and steering wheel position settings
● chassis and air conditioning settings
● custom settings such as interior lighting
You can input your own data in the
infotainment functions for your
vehicle as part of the selected
features.
Depending on the equipment level in
question, these include
● multimedia data such as music, videos or photos for playback in
an integrated multimedia system
● address book data for use with an
integrated hands-free system or an integrated navigation system
